>>4476117hey another gx680 chad, nice. i tore apart my mark 1 to diagnose an electrical gremlin and get a better understanding of how to power it since the batteries i got with it were dead. Fun stuff. rigged up an lp-e6 adapter that works pretty solid so the thing is firing away now. then i found out the chinks just have a purpose built solution for that on ebay and i could have saved myself the trouble lol, but it was fun to do. i have a mark 3 as well, and that one works without issues. it's a great fun system if a bit impractical. but like you i find the walking around with it (and a tripod lol) is fun.
